Abstract
Coatings on a titanium alloy are prepared by electrospark deposition with a non-localized anode consisting of titanium and aluminum granules with addition of chromium diboride powder. With increase of the CrB2 concentration from 2 to 10 vol.%, the gain in the weight of the cathode increases monotonically from 4.10 to 9.56 mg/cm2. According to the data of polarization tests and electrochemical impedance spectroscopy, the Ti – Al – Cr – B coatings reduce the corrosion rate of the VT3-1 alloy. The highest oxidation resistance of the coatings is observed for a CrB2 concentration of 2 vol.%. Deposition of Ti – Al – Cr – B coatings makes it possible to increase the surface hardness of the VT3-1 alloy by a factor of 2.7 – 4. The deposited Ti – Al – Cr – B coatings increase the wear resistance of the surface of titanium alloy VT3-1 by up to a factor of 6.
